             Summary: If changing version of flow and new flow has no 
connection to RPG Port, can get error saying unable to start components
                 Key: NIFI-4863
             Project: Apache NiFi
          Issue Type: Bug
          Components: Core Framework
    Affects Versions: 1.5.0
            Reporter: Mark Payne
            Assignee: Mark Payne

When we have a Remote Process Group with multiple ports, we push to the flow 
registry the ports that we have connections for. I have a connection to Port A 
and save that to the flow registry, then create a connection to Port B. I have 
RPG transmitting data. Then I revert local changes. This properly reverts the 
flow but fails to restart components. This is because it is attempting to start 
Port B, and there are no connections for that Port.
